Optical Burst Switch Network System And Method With Just-In-Time Signaling

US Patent:
2005001, Jan 20, 2005
Filed:
May 20, 2004
Appl. No.:
10/849204
Inventors:
Daniel Stevenson - Chapel Hill NC, US
Mark Cassada - Hillsborough NC, US
Pronita Mehrotra - Hillsborough NJ, US
International Classification:
H04B010/20
US Classification:
398060000
Abstract:
Optical burst switch network system and method with Just-in-Time (JIT) signaling and advanced data transmission and memory access and management. The system and method allow concurrent data transmission having arbitrary signal types, such as analog and digital signal types, in which the JIT signaling allows for subsequent simultaneous transmission of optical signals that do not require electro-optical conversion. The system includes an optical signal bus having a passive star coupler. A plurality of network adapters that are in optical communication with the optical signal bus and in network communication with network terminal devices are provided. The network adapters include receivers, transmitters and control logic that allows for bi-directional movement of data signals as bursts between the terminal equipment and the network system. The transmitter and receiver may be fixed or tunable. The system further includes an optical bus controller in optical communication with the optical signal bus that processes signals from the optical signal bus to connect a requested network adapter to a requesting network adapter in accordance with the user-to-network protocol. The network system implements a just-in-time signaling protocol to signal nodes in the network that burst communications are forthcoming. Optionally, the system allows comprehensive memory access in a Local Area Network (LAN). The nodes in the network are capable of seamlessly addressing memories of all other nodes that comprise the network.

Satellite On-Board Rfi Detection

US Patent:
2012002, Feb 2, 2012
Filed:
Aug 2, 2010
Appl. No.:
12/848549
Inventors:
Steven M. Lang - Cary NC, US
Mark C. Cassada - Hillsborough NC, US
Christopher M. Olson - Chapel Hill NC, US
Matthew K. Plonski - Morrisville NC, US
Assignee:
CISCO TECHNOLOGY, INC. - San Jose CA
International Classification:
H04B 1/38, H04L 27/06, H04L 27/00
US Classification:
375219, 375316, 375340
Abstract:
In one embodiment there are provided systems and methods for detecting radio frequency interference (RFI) on a satellite that implements on-board processing. The system leverages an on-board programmable modem complex, and in some cases reprograms portions thereof, to function as an RF spectrum analyzer sensor element that captures and relays received RF information as meta-data to a ground-based system where that information can then be used, on the ground, to generate a spectral display of a received signal at the satellite.

Inventors:
Pronita Mehrotra - Redmond WA, US
Dan Stevenson - Chapel Hill NC, US
Mark Cassada - Hillsborough NC, US
Wayne Dettloff - Cary NC, US
Assignee:
Research Triangel Institute - Research Triangle Park NC
International Classification:
H04J 14/02, H04J 3/16
US Classification:
398 48, 398 52
Abstract:
An optical network scheduling device () including a plurality of schedulers () each corresponding to a respective channel in the optical burst switch network and configured to maintain a transmission schedule for the respective channel; and a controller () configured to receive a burst transmission request and to select at least one of the schedulers as a selected scheduler schedule a burst transmission.

Methods And Apparatus For Constructing A Multi-Part Switch

US Patent:
2008025, Oct 16, 2008
Filed:
Apr 11, 2007
Appl. No.:
11/733867
Inventors:
Kevin Franklin Casey - Cary NC, US
Mark Cameron Cassada - Hillsborough NC, US
Frederic Michael Kozak - Raleigh NC, US
Kevin Craig Redmon - Durham NC, US
Assignee:
CISCO TECHNOLOGY, INC. - San Jose CA
International Classification:
H01H 13/14
US Classification:
200530
Abstract:
Methods and apparatus for providing a switch that includes multiple parts, and is arranged to function after extended periods of being in a depressed state are disclosed. In one embodiment, a multi-part switch includes a first contact, a second contact, and a plate. The first contact is electrically coupled to a first lead on a circuit board, and a second contact is electrically coupled to a second lead on the circuit board. The plate includes an electrically conductive area that contacts the first contact and the second contact to allow a signal to flow from the first contact to the second contact through the plate. In contacting the first contact and the second contact, the plate applies a compressive force to the first contact and to the second contact.
